Now that we have puppeh and megmeg as developers of gcc-6502 joining the discussion, it seems a good idea to have a separate english thread!
I already have a first question to puppeh: what do you think is the best thing to start on working to improve gcc-6502 support for the C64?
One thing we stumbled over is the charset conversion. I think gcc uses iconv to convert charsets, but that does not know about Commodore PETSCII out of the box. So I guess I will spend some time to create an iconv patch.
